为什么PHP不会转换特殊语言字符（例如韩语）？

Question

I have strings in different languages, such as Korean, encoded in UTF-8 (the strings).

I am trying to convert them into something like &#number; or ä etc. whenever possible, but using this in PHP:

   $str = htmlspecialchars($str, ENT_QUOTES);

doesn't do that.

What is the right way to do that?

Answer 1

You can use mb_convert_encoding like this:

mb_convert_encoding($str, "HTML-ENTITIES", "UTF-8");

As found here: Converting Korean characters into entities

Here's the man page for reference: http://php.net/manual/en/function.mb-convert-encoding.php
